newbie help on a list of users

I want to create a table that contains user info. From that list i want to be able to create a buddy list. for example:
I have 4 users bob, sally, jack and mary. Bob has sally, jack and mary as buddies. Sally has bob and mary as buddies. Jack has bob, sally and mary as buddies. Mary hase sally and jack as buddies. what is the best way to set this up? Thanks for any help.

You can make one table of users (userid, username,other info) and a table of buddies (user_id,buddy_id) that are both fks to userid in your users table. Each user-buddy pair then becomes its own row in buddies.
